Othonna is a genus of evergreen or deciduous geophytes, dwarf succulents or shrubs belonging to the sunflower family Asteraceae. The genus includes more than 100 species concentrated in the Western Cape of South Africa and southern Namibia. A few species occur in summer rainfall parts of southern Africa. The genus is closely allied to Senecio and can be distinguished principally by details of the involucre. Taxonomically they are in need of a modern revision.
